just starting off need some help

hey guys i was wondering if anyone knew any designs for homemade grow boxes and could help me out to build one for my closet for cheap. it is about two feet deep and i want the length to be no longer then 3 and a half feet

Here's a picture of mine...I bought mine, but it is VERY EASY to make.

All you need is a sterlite container (Linens and Things), some netpots (www.n-g-w.com).

Make holes in the container big enough for the netpots...the rest is history...here's a picture of my setup, works great and couldn't be any simpler.
